All the Feynman diagrams I have seen so far for a neutron colliding with a neutrino have a w+ with an arrow from the neutrino to the neutron.
Would it not also be possible with a W- leaving the neutron taking away negative charge for it to become a positive proton or is there some quantum rule I am not aware of that forbids this?
Any help gratefully received.
